A new promo video for the latest instalment in the Senran Kagura video game series tells of an exciting new piece of virtual-reality kit developed during production of the game. Whilst working on Senran Kagura: Estival Versus, apparently, some hard-working chaps in the “Department of Hyper Enormous Boobage Development” realised that the game’s female ninja characters’ chests were just not jiggling realistically enough. They set to work researching and designing the Pizap, a kind of treadmill add-on to gameplay in which players run after a well-endowed, bikini-clad woman and, er, watch her jiggle.

As you may have guessed, the Pizap is fictitious, as is Marvelous’s “Boobage Department” (although we do have to congratulate them on that name). But the promo video for it is real though, and it’s pretty hilarious. Join us after the jump as we check it out!

Except now. To celebrate the latest release in theSenran Kagura cute girl-ninja fighting game series, ramen shops all over Tokyo are serving special, limited-time only bowls of “boob ramen.” While that may sound awesome and hilarious at first, unfortunately the reality is quite different. Just take a look at what they’re offering.

Let’s play a little word association game. What’s the first word that comes to mind when you hear Senran Kagura?

I’m guessing at least a couple of you just said “Gesundheit.” Those of you who keep up on anime or Japanese video game releases, though, probably answered “Boobs.” After all, the Senran Kagura anime and video game series is about ridiculously oversized mammaries first, and ninja schoolgirl fighting action distantly second.

However, the problem with any long-running franchise is the risk of things growing stale, which would be especially problematic for Senran Kagura, because it’s hard to imagine something more unappealing than stale breasts. So after a half-dozen games, an anime TV series, and five different manga adaptations, Senran Kagura is poised to enter a new area: butts.

While plenty of video games use busty female characters to try to spice up their gameplay and drum up sales, few are as unabashed and exuberant in their mammary motivations as Senran Kagura. The bosomy brainchild of producer Kenichiro Takaki, Senran Kagura is an action title centered on a group of young female ninja that lets players fight hordes of enemies while staring at oversized, under-supported breasts.

Recently, though, a new round of inspiration smacked Takaki in the face, as he realized that cramming his series full of prodigious chests is only half of the equation of letting people play games with big breasts.

So he set out to design a game controller shaped like a pair of boobs.

Even though it was first released way back in 2012 in Japan, the rest of the world is only now getting its first taste of video gameSenran Kagura Burst. The Nintendo 3DS game saw a North American release last November, and was finally made available to European gamers just days ago.

But for an 18-month-old title to attract buyers who could be playing with their shiny new PlayStation 4s and Xbox Ones, Senrann Kagura Burst’s European publishers have to be very clear about what the game excels at, which is just what they’ve done with their tongue-in-cheek ads that make no bones about the game’s most distinguishing feature: gigantic bouncing boobs.
